Hi,Good afternoon from India. T
-Thanks for your query to My-HCM Clinic.
-I studied your query in depth.I understood your concerns.
-My opinion -You have 2 lumps-
a-neck lump-which is mostly-Sebaceous
Cyst.
b-hard penny sized ,which increased in last few weeks and now bigger and sensitive-mostly-this lump is -a boil with cellulitis-in hairline on the back of head.
Treatment-
Consult a Surgeon who would treat it with-
a-Neck lump-being sebaceous cyst-is Excision and
Biopsy. Cure -is by-Surgical Excision Biopsy by ER Surgeon.
b-Lump on back of Head-being -a Early un-ripe boil-which would regress after Antibiotics and Tb NSAIDs.
-Hope this would help you to recover from worry-some query.
Wish you a Fast Recovey.Wellcome to HCM again.
